Problems with non FullHD movies over Media Player

I’m getting distorted playback of mp4 movies which are non FullHD in Unreal MediaPlayer. Optimally I just need 1366x768 (is 16:9) movies because that is my target system full screen resolution and have to use FullHD Movies because everything else looks out of sync.
This is the output of the 1366x768 video:

123835-1366x768.jpg
123835-1366x768.jpg1148×649 142 KB

Instead of the FullHD video:

123839-fullhd.jpg
123839-fullhd.jpg1148×649 85.2 KB

It looks like the player misread the line width and offsets every following video more and more. I’v tried multiple mp4 encoder and setting so this shouldn’t be the problem. Had this problem with multiple resolutions and aspect ratios.
Don’t be puzzled by the slihhtly distorted look of the FullHD screenshot, my canvas is a media Texture on a more quadratic object, and because only FullHD is working I couldn’t encode a horizontal smaller video to 1:1 match the canvas. Videofiles are prerendered in FullHD and 16:9 and 1:1 encoded to 16:9.

Problem should be easy to reproduce, simply use the video in media file source and watch in media player in editor. Packaged app shows the video distorted the same or sometimes don’t show it at all. If wrong in editor → wrong in package.

Thanks vangel, I added your video to my test collection. I’m pretty sure this is fixed in 4.15. In the meantime, what you can do in 4.14 is to make sure that your video’s width is divisible by 16. That will fix the problem.

I noticed that your video uses QuickTime’s AVC1 encoder. Please be aware that this may not work on all PCs if QuickTime isn’t installed. A more compatible encoder would be H.264.

I can assure you it must be a false metadata, the codec is pure H.264 embedded in a mp4 container, runs fine without Quicktime. Adobe probably write this crap into the file so Macs will play it without questioning themselves ;-).

I’m having this exact issue in 5.23 with any codec that isn’t divisible by 16, only in windows. Any ideas?
